11. Role of respiratory supercomplexes : Electronic connection between complexes III and IV
Sammanfattning : In the final step of cellular respiration, electrons are transferred through the respiratory chain to reduce molecular oxygen to water. The energy released in this chain is used to maintain a proton electrochemical gradient across the cell membrane, which is used, for example, by the ATP synthase to produce ATP. LÄS MER
12. Cytochrome c Oxidase dysfunction in cancer : Exploring the molecular mechanisms
Sammanfattning : Mutations in genes encoding the mitochondrial enzyme Cytochrome c Oxidase (CytcO) have lately been found in connection to various types of cancer. Some mutations result in substitutions of highly conserved amino-acid residues. LÄS MER
13. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems
Sammanfattning : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. LÄS MER
14. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes
Sammanfattning : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

15. Membrane effects on proton transfer in cytochrome c oxidase
Sammanfattning : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. LÄS MER
